Infant feeding chart by age and weight
By The Baby Care Cards teamUpdated 5 min read
Short answer
As a general guide, newborns take around 1.5 to 3 ounces per feed in the early weeks, rising to about 4 to 6 ounces per feed by 4 to 6 months, then gradually replacing some milk feeds with solids from 6 months onward. These are general planning ranges only — always confirm the right amount for your baby's age and weight with your pediatrician or the guidance on your formula packaging.
The app does not provide medical advice or recommend medications or dosages. It only helps parents organize instructions they provide. Always follow your pediatrician.
Portion sizes change quickly in the first year as babies grow and, later, start solids. This chart gives general planning ranges so you can write an accurate schedule for a caregiver, but it is not a substitute for your pediatrician's guidance on your specific baby.
General ranges by age
These ranges are for formula-fed babies as a planning guide; breastfed babies typically feed on demand and volume is harder to measure directly. A baby's weight, growth rate and appetite all affect the right amount, so treat this as a starting point for conversation with your pediatrician, not a target.
- 0 to 2 weeks: roughly 1.5 to 3 ounces per feed, 8 to 12 feeds a day.
- 1 to 2 months: roughly 3 to 4 ounces per feed, 6 to 8 feeds a day.
- 3 to 5 months: roughly 4 to 5 ounces per feed, 5 to 6 feeds a day.
- 6 to 8 months: roughly 5 to 6 ounces per feed alongside introducing solids, 4 to 5 feeds a day.
- 9 to 12 months: milk feeds reduce as 3 solid meals plus snacks are introduced.
Signs your baby is getting enough
- Steady weight gain, tracked at checkups
- Regular wet and dirty diapers appropriate for age
- Generally content between feeds
- Alert and active periods during the day
Signs to check with your pediatrician
- Consistently refusing feeds or taking far less than usual
- Poor weight gain at checkups
- Excessive spit-up or signs of discomfort after feeding
- Fewer wet diapers than expected for age
Writing this into a caregiver's schedule
Once your pediatrician has confirmed the right amount for your baby, write the exact figure into your care card rather than a range, so a sitter or grandparent is following your baby's real numbers, not a general chart.
Frequently asked questions
- Is this chart accurate for my baby specifically?
- It is a general planning range only. Premature babies, babies with reflux, and babies with other medical needs often follow a different schedule set by their pediatrician, which should always take priority.
- How do I know if I should increase the amount per feed?
- Watch for consistent hunger cues shortly after a feed and confirm with your pediatrician at the next checkup rather than adjusting amounts on your own.
